Question
Find the diameter of a circle whose circumference is:
88m.
88m.
✓
Answer
Let the radius of the circle be r m.Circumference of the circle (C) $=88\text{m}$
$\Rightarrow2\times\frac{22}{7}\times\text{r}=88$
$\Rightarrow\text{r}=\frac{88\times7}{2\times22}=14\text{m}$
Now, diameter $=2\times\text{r}=2\times14=28\text{m}$
$\Rightarrow2\times\frac{22}{7}\times\text{r}=88$
$\Rightarrow\text{r}=\frac{88\times7}{2\times22}=14\text{m}$
Now, diameter $=2\times\text{r}=2\times14=28\text{m}$
